Much-branched tap-rooted herb 20-40 cm tall and diam., with a perennial rootstock; stems and branches moderately to densely woolly-cobwebby with underlying inconspicuous glandular hairs; leaves linear to oblanceolate, with a recurved, sometimes undulate margin, acute to apiculate apex, and a broadly sessile base, mostly 0.5-1.5 cm long, 1.5-3 mm wide, glandular-scabrid and additionally with a sparse to dense vestiture of woolly-cobwebby hairs, especially on the underside.
Peduncles 1-3 cm long, with a few distant much-reduced leaves, terminating leafy branches; capitula broadly campanulate to hemispherical, 6-8 mm long; involucral bracts graded in length with the inner ones longest, all or most with a glandular and cobwebby vestiture, with long-ciliate margins, the cilia in length about equal to the width of the bracts, the majority of bracts hyaline to scarious with more or less opaque tips, a pale golden-yellow, the outer ones linear-lanceolate, the inner ones with linear herbaceous glandular-pubescent claws and narrowly ovate-acuminate laminae; florets exceeding the involucre by c. 2 mm.
Achenes oblong, compressed, papillose; pappus-bristles of the bisexual ones 5-8, barbellate towards the base, penicillate at the apex, of female ones absent or 1.
